The Laser ablation technique is dominantly used for in situ analysis of geological samples to study trace elements concentrations
and zonations in minerals and rocks.

The technique involves removal of mass from solid samples by application of laser energy.

The ablated / removed mass of sample is then analysed by a suitable analytical technique.

At LAICPMS, Laboratory GSI, Faridabad a CETAC Nd:YAG 213nm Laser Ablation (LA) System coupled with Agilent 7700 Inductively
Coupled Plasma – Quadrupole Mass Spectrometer [ICPMS (QP)] is used to analyse the composition of the sample with sensitive detectors
that measure concentrations in the parts per billion

Standard Operating Procedure

Capabilities:

The technique is extremely useful for trace element and REE analysis of minerals up to concentration in part per billion (ppb).

To determine the bulk composition of rocks by pellet preparations and fusion beads
